Unhappy customer

last year may I have bought a 70" JVC smart TV from PNP hyper in klerksdorp north west and ever since I have received the TV the experience have been nothing short of distraught and heartache for me as a consumer. Few days after receiving the product it started acting up like it would freeze in the middle of entertainment and restart itself which I didn't really take it to head as I was still able to watch afterwards but in January this year something out of the ordinary occured where the TV was showing that it is on but not displaying anything which I immediately took it back to the seller and logged a technical fault call which took the whole month to be fixed. I just received my TV back 2 days ago which I was happy to be able to enjoy my hard earned money again but to my suprise that did not last as I woke up this morning to a TV that is not working not even switching on, mind you taking this back and forth cost me over a thousand already for transport fee. all I want is my money back because it does seem like this product is a distortion of a consumer's money which shouldn't even be on the shelves to be sold to people. I have heard about similar occurrence from other consumers even shop consultants.
